Roger Federer says “now is the time” for the men’s and women’s governing bodies to merge while tennis is in limbo because of the coronavirus.
The 20-time Grand Slam champion floated the idea in a series of Twitter posts.
He said a merger of the Women’s Tennis Association (WTA) and the men’s Association of Tennis Professionals (ATP) “probably should have happened”.
“We can come out of this with two weakened bodies or one stronger body,” Federer said.
Later on Wednesday ATP chairman Andrea Gaudenzi appeared to back the idea saying: “Our sport has a big opportunity if we can come together in the spirit of collaboration and unity.
“Recent cooperation between governing bodies has only strengthened my belief that a unified sport is the surest way to maximise our potential and to deliver an optimal experience for fans on site, on television and online. To that end, I welcome the views of our players.”
BBC Sport understands preliminary discussions have taken place between the two tours about greater collaboration in certain areas.
In a series of social media posts on Wednesday, Federer added: “I am not talking about merging competition on the court but merging the two governing bodies that oversee the men’s and women’s professional tours.
“It’s too confusing for the fans when there are different ranking systems, different logos, different websites, different tournament categories.”
American tennis legend Billie Jean King, one of the prime movers behind the founding of the WTA, said a merger “has long been my vision for tennis”.
“The WTA on its own was always Plan B,” added King. “I’m glad we are on the same page. Let’s make it happen.”
Spanish 19-time Grand Slam champion Rafael Nadal added: “It would be great to get out of this world crisis with the union of men’s and women’s tennis in only one organisation.”
Reigning Wimbledon champion Simona Halep, two-time Wimbledon champion Petra Kvitova, Argentine Diego Schwartzman and two-time Grand Slam champion Garbine Muguruza are among the other high-profile tennis players to voice their agreement on social media.
All tennis has been abandoned until at least 13 July, with Wimbledon cancelling its grass court tournament for the first time since World War Two because of the coronavirus pandemic.
It followed the postponement of the French Open, which was due to begin in May but has been rescheduled to take place in Paris from 20 September to 4 October. (BBC Sports)
